Definitions

  • the invention relates to a method for changing roving bobbins on a spinning machine, in particular a ring spinning machine with a four-row spool arrangement in the creel according to the preamble of claim 1.
  • the invention also relates to a device according to the preamble of Claim 11.
  • EP 311 862 shows a device for changing roving bobbins, with bobbins being transported on creel rails by a transport suspension conveyor along the ring spinning machine along with sections of a transport unit that can be moved on the suspension conveyor.
  • the cross rails of the two long sides of the ring spinning machine are separated and each cross rail has a holding capacity of two coils in a four-row coil arrangement in the creel.
  • a relevant section in this case has two coils and, after this section has been decoupled from the transport unit, reaches the relevant cross rail by changing the direction. Automation is limited to decoupling and moving the transport unit using friction rollers. An operator must take care of moving a section with full spools onto the cross rail and moving a section with empty spools from the cross rail onto the overhead conveyor. In addition, switches are necessary between each cross rail and the monorail.
  • a driven coil converter also known as a traveling switch or trolley, is provided here.
  • This coil converter runs parallel to the monorail above the gate and is with the To bring the transport unit into engagement in such a way that the transport unit can be towed by the coil converter.
  • the coil converter can let the transport unit pass itself by means of a gear wheel or friction wheel.
  • the transport unit has an unchangeable, predetermined length and carries coils with it via coil carriers.
  • the coil carriers are detachably connected to the transport unit, the coil converter pushing the coil carriers onto the cross rail.
  • the bobbins are shifted in one direction towards the machine center plane, with empty bobbins of the inner longitudinal row of work spools being brought onto drivers of a clearing belt arranged in the middle of the machine.
  • the empty bobbins are returned from the clearing belt to the transport unit via one of the cross rails, the bobbin converter again being able to be used.
  • an additional longitudinal row of reserve coils is required on each machine longitudinal side, which broaden the creel.
  • the mode of operation of this bobbin change basically consists in that a transport unit fully loaded with full bobbins is moved to the gate, that all full bobbins are delivered on cross rails, whereby the transport unit is completely emptied, that the empty bobbins are located above the machine center level - Area and a cross rail provided therefor are brought back onto the transport unit, after which the transport unit, fully loaded with empty spools, is transported away from the gate again.
  • the invention in a second aspect, relates to the automation of the gate feed for spinning machines or twisting machines which require a template in the form of a spool.
  • the invention is particularly designed for ring spinning machines, from which the individual spinning stations are fed by roving bobbins.
  • the description focuses on ring spinning machines with a roving template as an example.
  • the invention is not restricted to this type of machine or template.
  • a twisting machine for example, needs a thread spool as a template. Accordingly, the limitation to a roving as feed material is dispensed with in the claims.
  • a ring spinning machine works as the last link in a chain of processing machines that transform disordered fiber material into a yarn.
  • the spinning machine is accordingly restricted by the capabilities of the machine supplying it, in particular the flyers (pre-spinning machines) preceding it.
  • flyers pre-spinning machines
  • This also applies to a transport system that connects the two machine types.
  • the technology of ring spinning has been put into practice and developed further for more than a century and today its basic features are largely standardized. In order to ensure the efficiency of the process and competitiveness, there is an urge to make optimal use of the space available in the spinning room. No single spinning position of a ring spinning machine can therefore be regarded as an island.
  • the spinning positions of the individual machines are arranged as close together as possible.
  • the machine has a "double-sided" design, ie the spinning positions are arranged in two rows, each on one machine side.
  • the machines themselves are crowded together in the spinning room.
  • the remaining space systems for automatic 'Transport ⁇ and coil handling robot is therefore limited and can hardly be increased without increasing the competitiveness of the process itself (ie, the efficiency of the Ge plete solution) to compromise.
  • the roving bobbins are each formed on a sleeve (as a supporting element) and are vertically suspended from the individual spigot in order to feed a respective spinning position in the so-called creel.
  • a sleeve as a supporting element
  • the bobbins for approximately one row of spinning stations must therefore be arranged in at least two rows above the spinning stations.
  • the roving is pulled off to the side and then runs downwards via guide elements into the drafting system of the spinning station.
  • DOS 1969002 A first attempt at automated gate loading is included in DOS 1969002.
  • this DOS concentrates on a transport system for bringing flyer coils to the ring spinning machine and is otherwise limited to indications regarding “automatic devices” which have neither been described nor shown.
  • a partial solution consists in simultaneously clearing and reloading a whole row or even a whole "machine side" by "longitudinally extending” or “longitudinally retracting”. Proposals of this type can be found in US 3828682 and DOS 3709540 (US 4827709), with a spare row being provided in DOS 3709540, so that spinning can be continued without interruption. However, these solutions do not include any suggestions for the automatic operation of the newly introduced ones Coils in, ie they mainly concentrate on the transport tasks. The question of further expansion to a fully automated system remains open with such partial solutions.
  • DOS 3208677 A substantially similar system is included in DOS 3208677 (US 4438622). The main difference is that according to DOS 3208677 the new roving should not be attached to the old roving.
  • the description in DOS 3208677 is at least incomplete in that it stops inserting the new fuse into a funnel upstream of the spinning station. The way in which the spinning station is to be put into operation in this way is neither described nor indicated in DOS 3208677.

Abstract

Une unité de transport (21) se déplace sur une voie suspendue (18), apportant des bobines pleines (12) au râtelier (5) d'un métier continu à filer à l'eau (4) et emportant des bobines vides (13) du râtelier. Un dispositif (22) de transfert des bobines est entraîné sur des rails de roulement (41) au-dessus du râtelier (5). Dans le râtelier (5) sont agencés des rails (15) perpendiculaires par rapport au plan médian (8) du métier. Le dispositif (22) de transfert des bobines transfère premièrement les bobines vides (13) d'un rail du râtelier à l'unité de transport (21). A cet effet, des places vides pour au moins deux bobines doivent être disponibles sur l'unité de transport (21). L'unité de transport (21) est déplacée par le dispositif (22) de transfert de bobines, puis ce dernier transfère les bobines pleines (12) de l'unité de transport aux rails vidés (15) du râtelier.
